    Insights

    Azathioprine, a medication used to suppress the immune system, was found to be mutagenic in Salmonella typhimurium bacteria. This mutagenic effect was only observed when the bacteria were incubated anaerobically with the drug.

    Area of Science:

    • Microbiology
    • Toxicology
    • Pharmacology

    Background:

    • Azathioprine is an immunosuppressive drug.
    • Understanding the genotoxic potential of pharmaceuticals is crucial for safety assessment.

    Purpose of the Study:

    • To investigate the mutagenicity of Azathioprine.
    • To determine the conditions under which Azathioprine exhibits mutagenic effects.

    Main Methods:

    • Bacterial mutagenicity assay using Salmonella typhimurium.
    • Incubation of bacteria with Azathioprine under both aerobic and anaerobic conditions.

    Main Results:

    • Azathioprine demonstrated mutagenic activity in Salmonella typhimurium.
    • Mutagenicity was observed specifically during anaerobic incubation.

    Conclusions:

    • Azathioprine possesses mutagenic properties.
    • Anaerobic conditions are required for the detection of Azathioprine's mutagenicity in this bacterial model.

    Mismatch Repair

    Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.

    Mutagenicity and Carcinogenicity

    Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...

    Drugs for Treatment of Ulcerative Colitis in IBD

    Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide generation.

    Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

    Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel Disease...

    Pharmacogenetics of Phase II Enzymes: N-acetyltransferase, Thiopurine S-methyltransferase, UDP-glucuronosyltransferase

    Phase II biotransformation reactions are essential for detoxifying and eliminating xenobiotics, including many pharmaceutical compounds. These reactions typically involve conjugation, the covalent attachment of polar endogenous groups such as glucuronic acid, sulfate, methyl, or acetyl moieties to functional groups introduced during Phase I metabolism. The resulting conjugates are more water-soluble, enabling efficient renal or biliary excretion.The major classes of Phase II enzymes include...
    Spontaneous and Induced Mutations01:30

    Spontaneous and Induced Mutations

    Spontaneous mutations arise infrequently during DNA replication due to errors in the process. A key factor behind these errors is tautomeric shifts in nitrogenous bases, where bases transition from keto to enol forms or amino to imino forms. This shift can alter base-pairing rules, leading to mutations. Additionally, reactive oxygen species (ROS) arising from aerobic metabolism can damage DNA, resulting in depurination (loss of a purine base) or depyrimidination (loss of a pyrimidine base).
